Two birds collide in midair. Before the collision, their combined momentum was 88 kg•m/s to the west. What is their combined momentum after the collision?
A. 88 kg•m/s east
B. 88 g•m/s north
C. 88 kg•m/s down
D. 88 kg•m/s west
NEWTON'S FIRST LAW !!!!!!!!!!!
There is NO external force on this system
therefore
There is NO CHANGE of momentum.
Never ever forget that !!!
D. !!!!!!
That did it !
Here in texas, they often fall to the ground after collision... :)
LOL, it was about the horizontal plane, but yes that could happen
To solve this problem, we need to understand the principle of conservation of momentum. According to this principle, the total momentum before a collision is equal to the total momentum after the collision, assuming no external forces are acting on the system.
Given that the combined momentum of the two birds before the collision is 88 kg•m/s to the west, we can conclude that the total momentum after the collision must also be 88 kg•m/s to the west.
Therefore, the correct answer is D. 88 kg•m/s west.
